Representative models
Reactive Power Compensation Controller
The Reactive Power Compensation Controller is a fully digital device with AC sampling and a large-screen LCD Chinese interface. It displays real-time power factor, voltage, current, active power, reactive power, voltage and current THD, frequency, capacitor output and switching status, and alarms for L1, L2, and L3.

High-Voltage SVG Dynamic Reactive Power Compensation System
The High-Voltage SVG Dynamic Reactive Power Compensation System (ZSBKSVG series) is an IGBT-based reactive power compensation system that provides continuous capacitive or inductive reactive power. It supports constant reactive power, constant voltage and constant power factor control at the measurement point. Installed near special loads such as arc furnaces, medium-frequency furnaces and refining furnaces in distribution networks, it improves power quality at the point of common coupling, including power factor, three-phase voltage balance, voltage flicker and fluctuation suppression, and harmonic mitigation.
